[5.x]: Passkey login doesn't work

[matthewstick]

What happened?

Description

Can't log in using passkey

Steps to reproduce

1. Add apasskey to my user account.
2. I use the keychain to do a thumbprint from my laptop. It works and gets added.
3. Go into the CMS login screen and click "log in via passkey". I click it. It prompts me for my thumbnail. It says you will be signed into domain name via the passkey saved in email address
4. It does not work.

Site is on Craft Cloud btw, but not sure if that matters.

Expected behavior

It should log me in.

Actual behavior

I don't get logged in.

• What browser + version are you using?
• What is your laptop’s make/model?
• Is the fingerprint scanner built-in, or an external peripheral?

I tried both the latest chrome and latest Safari right now
Chrome: Version 126.0.6478.183 (Official Build) (arm64)
Safari: Version 17.5 (19618.2.12.11.6)
Mac: MacBook Pro, 14-inch, 2021, Apple M1 Max, OS Sonoma 14.5 (23F79)

I enter my email -- no password obviously -- click "sign in with a passkey" -- then I use the built in thumbprint button to authenticate. Its a button in the top right of the keyboard. The thumbprint button gives me a check like it worked (step 2), but it then doesn't work on the Craft CMS side and gives me those errors (step 3)

I've attached screen shots, obfuscating my email and the domain.

Step 1

Step 2

Step 3

Here is my user profile. It says "last used" this morning, but really it never got used. That's when I added it via keychain and it put my thumb and it worked. I kept the default title "Chome on Mac," which is the browser I was using when I added it.

So not Linux then 🙃

Just tested on Safari and was able to sign in successfully.

Couple things to try:

• Run composer update
• Enable the safeMode config setting to rule out any plugin/module conflicts
• Have your JavaScript console open and see if any JS errors / non-200 requests are occurring on the Login page throughout the process
